[ARC5] Carbon mic pops

[hwhall at compuserve.com]

I have a question about use of carbon mics in circuits like interphones. Mics like the T-17 leave the mic "battery" current circuit open until the PTT is pressed to speak. But the contact closure creates a huge pop in the headphones attached to the amp output. Does anyone know how this was dealt with or did they just live with the earsplitting pops??
